For my baseboards/casings, most of it looks like it's going to be fairly straightforward. My stairs are the pre-assembled kind; the skirting board has routed-out slots to fit the treads/risers. At the top of the stairs, the skirt board ends only about 1.5" higher than the floor level, so I'll just have my baseboard flow continuously onto the skirtboard, then along the skirtboard, all the way down the stairs. At the bottom of the stairs, the skirt board ends several inches from the floor level, so I'll need to have a miter to make it go vertical for a few inches, then an other miter to make it go back horizontal to join the baseboard on the lower floor. No issues so far.
Now at one of the staircases, the stairs end right at the end of a wall, so I don't have enough room to go vertical and then horizontal (ignore the babygate and the gross carpet):
I tried to figure out a way to get this baseboard stuff to look nice:
- go horizontal a few inches before the end of the wall, go around the corner, then miter to vertical, then down, then miter to horizontal, then around the other corner
- add a return downwards (i.e. into the skirtboard), then have the bottom floor's baseboard all the way around the corner then do a return.
- can't really do a return "into the wall" because I'm not horizontal
I think that's the cleanest thing I can do. The skirtboard doesn't extend all the way to the end of the wall (~0.5" missing), so I thought I'd use some kind of wood filler to extend it (maybe a thin piece of wood to make up the bulk of the volume to fill, then filler).
My other area of concern is the flooring height transition between the kitchen (cement board plus porcelain tile) and the stair landing (laminate). The laminate is 12mm plus 2mm padding; the tile is 9.8mm plus 6.35mm cement board plus thinset. So I imagine the tile will be about 10mm higher than the laminate.
I see three options:
- Have the baseboard do a height transition in the doorway (e.g. do 20 degree up, then 20 degrees down)
- Rip the baseboard where the floor is highest (baseboards are 3 7/8" tall)
- Raise the landing by plywood to match the height of the tile (3' by 7' area)
